They've finally posted it! The 2013 Lightning Lap feature is finally available online (full article: Lightning Lap 2013: Hot Cars, Hot Track, Hot Laps ). I know it has been available in the February issue but I don't buy the magazine so I haven't been able to read it until today. It is kind of bittersweet for me though. You see, I love the Lightning Lap feature. They test all the performance vehicles that either came out or were upgraded the year before. This makes it a very exciting event/test but it also means that there is only 1 Lightning Lap feature in a year, so I am both excited for the new one and disappointed that I have to wait for a year for the next one. Anyhow, for road racers and track day veterans, it is a great test (or set of tests). There are many reasons why the Lightning Lap feature is great IMO. Except for the SUV class, which includes vehicles like the Jeep SRT and BMW X5 M regardless of prices, cars are divided in classes depending on price ranges...
I'm finishing up a comparison post (link to introduction: Intro: Focus RS vs Golf R vs WRX STI vs Evo X ) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much. By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the...
